基于Matlab的某4WS越野车建模与仿真
Modeling and Simulation of a 4WS Off-road Vehicle Based on Matlab
摘要
Abstract
Based on the three degree of freedom 4WS model and zero sideslip angle feed-forward con⁃trol, a 4WS off-road vehicle simulation model was established by the Matlab software, and the response parameters were analyzed in time and frequency domain, the results show that comparing with 2WS, the sideslip angle of 4WS is reduced obviously based on feed-forward control in time domain analysis, so the capacity of path tracking is better than 4WS. Mean while, the handling and mobility at low speed and the stability and safety at high speed of 4WS are enhanced when steering, and the transient re⁃sponse is better as well. The frequency domain analysis shows that the output response of 4WS can car⁃ry out the input order well when the driver turns steering wheel slowly at different low frequency, and the phase delay is not big, so the vehicle handling stability of 4WS has good dynamic characters.关键词
